  1. Hello guys,

     

    I'm in the process of creating a new unRAID PC, I've been searching a lot and trying to adjust to Europe options when it comes down to rack mount cases. I've found this one http://inter-tech.de/index.php?option=com_content&view=article&id=1139%3Aipc-4u-4410&catid=136%3A4u-storage-gehaeuse&Itemid=961〈=en which seems pretty good for my needs. HOWEVER it has a note in the product's description:

     

    By use in combination with an Intel Onboard SATA-Controller the Controller has to be set to Raid-Mode (Hot-Plug will be set automatically) or every port separately to Hot-Plug/ external Port (depends on your Bios). If these settings are not available in your Bios, maybe an error-free use is only possible by using an additional SATA-Controller.

     

    Is normal to change this setting in BIOS in these hot swap cases? is this going to create problems with unRAID?. Thanks a lot for any info

  2. I'm also interested to know if I can create a RAID0 with SSDs and use them as cache + another SSD for parity

    You can use BTRFS RAID0 on SSDs and use them for cache if you want to, but the use of an SSD as a parity drive is not supported.

     

    Oh, I was almost sure that you could select an SSD drive to be a parity of another SSD acting as cache :o. How do you do to make sure your cache data is safe then? just back it up to your HDDs?

     

    When you said "parity" I assumed you meant unRAID's parity disk(s). Do you actually mean some form of protection for the cache disk? If you do then just use BTRFS for the cache pool. If you then have a cache pool of two SSDs they will be set up as a RAID1 mirror. So a pair of 250 GB SSDs would give you 250 GB of protected cache. If that isn't enough you could use four 250 GB SSDs to give you 500 GB of protected cache. Various other combinations are also possible, such as three 250 GB SSDs to give you 375 GB protected, or two 250 GB and one 500 GB to give you 500 GB protected.

     

    Thanks! My idea was to improve the speed by doing a RAID0 (2x250gb = 500gb RAID0) and use another SSD for example a 500GB for parity. If there's no support for parity per se, then I guess I would need to do 2xRAID0 in RAID1?. BTW, the RAID is created on unRAID or is it created on MB's RAID controller?

    I'm still waiting components to arrive. One of the things I'm still missing is the case. I've been searching a lot and trying to adjust to Europe options. I've found this one http://inter-tech.de/index.php?option=com_content&view=article&id=1139%3Aipc-4u-4410&catid=136%3A4u-storage-gehaeuse&Itemid=961〈=en which seems pretty good for my needs.

    Is this normal in these hot swap cases? is this going to create problems with unRAID?

     

     

    OK, First thing!  unRAID is not RAID, hence its name!  I believe that unRAID does not support 'hot swapping' of drives in any case.  However, the use of 'hot swap' drive bays is recommended by many of us.  They make the addition and changeout of drives so much easier which is a minor point.  What their use does do is to prevent problems when one has to open up a case, unplug a drive, and get it physically out of the case and reverse the process to get a new one installed.  If you are familiar with SATA connectors, you should have realized by now that they are the mechanically deficient connector arrangement that has ever been put into wide use.  It  is not a bad situation when you are only dealing with two or three drives but when you have more than seven or eight, the rat-nest of wire harnesses becomes unmanageable and loosing one connector while working on another seems inevitable.  Plus if they are loosened up a little, they can vibrate off at a later time.  Therefore, the use of hot=swap' cages is the norm for experienced unRAID users as I don't believe that there is any front quick-change drive housing that is not a 'hot-swap' compatible one.

     

    Hello Frank, thanks for your reply. Indeed, I was aware that I will have to turn off the computer to manage drives... but as you said it's much easier to have these hot-swap cases for that matter.

     

    However what worried me is what the case's description was saying, do you know if this is normal on any hot-swap case? or should I avoid these kind of cases requesting changes in the BIOS, etc?

  6. What did you end up going with? Also which case are you using?

     

    You're build is similar what I would like to do so I'm curious :)

    Here's the list:

     

    • CPU: Intel Xeon E3-1230 v5 (TDP 80w), 9277 Passmark (it costs 100€ less than 1275!, but no integrated GPU). Can I use the IPMI port with unRAID or do I need a GPU?
    • MOBO: Supermicro X11SSH-LN4F https://www.supermicro.nl/products/motherboard/Xeon/C236_C232/X11SSH-LN4F.cfm SATA x8, LAN 4x
    • RAM: Kingston ValueRAM 8GB DDR4 2133MHz Module ECC 15-15-15-33 (2x8GB)
    • Power: Corsair RM550x 80+ gold single rail
    • Disks: 2x4TB WD RED NAS, 1x3TB WD, 1x2TB WD, 1x500GB WD, 1x250GB SSD Samsung Evo 850 (these are the disks I currently have)

     

    For the case, I will go with a rack-mount 4u, just not sure which one yet... but I'd like to have at least 8 hot swappable trays!

     

    Thanks! Have you chosen a heatsink yet?

     

    Keep us updated on how the build goes.

     

    Yep! Will go with this one http://noctua.at/en/nh-d9l

  8. Thanks all again, I've updated the MB and CPU list.

     

    About CPU, the E3-1240 and E3-1240L cost the same, but the L version has a much lower TDP, interestingly it doesn't go in proportion with the Passmark points, so it seems to be VERY energy efficient as it has around 70% of 1240 performance but a much lower TDP. Am I missing something here? or it's just that good?. BTW, the integrated graphic in the CPU can be used for unRAID? (I read it will need one graphic card)

     

    For the MB, I've found these 2 options which seems quite good. I particularly like the 4 LAN ports as I could passthrough 2 of them to a pfSense VM and sell my current MacMini which has pfsense on it. They both have 8 SATA ports, which will be ok for a while... then I guess I will just have to replace some disk or buy an external SATA controller

     

    Do you have any more suggestions or ideas? Any hardware incompatibility you can think of? Thanks for all the help!

  9. Here's a few things I would like to do:

    • 6-8 HDD + 2 SSDs for cache. Not sure if there's support for PCIe SSDs with NVMe?
    • Backup 2 Macs through TimeMachine (one thing is not clear to me, I know unRAID support AFS but not sure if there's a chance to create a valid TimeMachine volume for usage?)

    There are nvme support in 6.2 beta, not in 6.1.9

    Yes you can create a TimeMachine share.

    Thanks! that's great :)

  10. Hello guys,

     

    I think this is my first post in the forum but I have been reading for like 2 months. I'm loving more and more unRAID and wanted to give it a try. I currently have a QNAP NAS which is quite slow and 'dumb' if you ask me. I think unRAID will be a much better fit for me.

     

    So I'm looking to build a rackmount case, my goal is to have a powerful machine with low consumption and silent, really silent. It will be turned on 24/7. I'm not going to do gaming for now, but I might in the future.

     

    Here's a few things I would like to do:

    • It's ok for me if the hardware is workstation or server level. It's not a must to run ECC memory, for example.
    • 6-8 HDD + 2 SSDs for cache. Not sure if there's support for PCIe SSDs with NVMe?
    • Motherboard with at least Dual LAN (a good ones, from Intel)
    • Expandability for future proof, for example have a few PCIe for to add more NICs or to install a good GPU. My idea is to buy a rackmount case 4U.
    • Dockers I will be running all the time: PlexMS, jDownloader, Torrent, Homeassistant, influxdb, grafana, homebridge, Couchpotato and ivideon. More could come
    • I usually do a direct play with Plex, but having enough power for 2 1080p transcoding would be enough (maybe future proof-it for 4k) so I guess around 8000-10000 passmark points could do it (rule I read on the forum was 2000 passmark for every 1080p transcoding)
    • A couple of VMs (usually Win8 and Win10) but these are for testing and won't be running all time nor will be doing CPU-intensive tasks
    • IPMI port (or similar), I need this yes or yes! It's awesome :)
    • Backup 2 Macs through TimeMachine (one thing is not clear to me, I know unRAID support AFS but not sure if there's a chance to create a valid TimeMachine volume for usage?)

     

    MB (I'm adding new ones as I discover them. Let me know if you have any suggestions considering all the info I provided)

     

    CPU (need an integrated graphic card either in the CPU or in the MB)

    • Intel Xeon E3-1240L v5 (TDP 25w), 7157 Passmark.
    • Intel Xeon E3-1240 v5 (TDP 80w), 10177 Passmark.
    • Intel Xeon E3-1275 v5 (TDP 80w), 10342 Passmark (integrated GPU)
    • Intel Xeon E3-1230 v5 (TDP 80w), 9277 Passmark (it costs 100€ less than 1275!, but no integrated GPU)

     

    For budget, well I think around 800€ for CPU + MB. I don't have any spare parts to use in this rig.

     

    Current build idea

    • CPU: Intel Xeon E3-1230 v5 (TDP 80w), 9277 Passmark (it costs 100€ less than 1275!, but no integrated GPU). Can I use the IPMI port with unRAID or do I need a GPU?
